Hello cousin. Your Samuel Gange was probably the son of Samuel b. 1856 in Oswego. He apparently died in WA. Might also have been the son of Wm Henry and Amelia Chartier or of Edwin Gange who supposedly died in a theater fire in St. Joseph, MI. All are the children of Edwin Humphrey and Ann Baldwin both b. in ENG. My grandmother was a sister. I may have met your Sam when I was back in Oswego on one of several trips. If not him then a son. I have info on this family but can't get them past Canada from whence they migrated to Oswego about 1853-55.
At last I have found someone else working on the Ganges. Please contact me. Dean Gernon
